L98 Fuel Injectors
I see a lot of em on eBay for around 89 bucks for all 8. A lot of times even cheaper than that.
So why should I spend over 200 bucks for the remanufactured Bosch III ones from a preferred vendor?
This is not to pick on anyone, it's a legit question that I have.
Both are remanufactured. And I'm pretty sure both probably have the same 1 year waranty, though the vendor selling the Bosch ones doesn't actually say anything at all about a warranty.
The Bosch ones are supposedly made in the USA.
The solder on the inside of the brand new Bosch starter I bought broke when I was tightening the wires down when I was installing it right out of the box. So in my experience, the Bosch brand doesn't really mean quality, per se. Yeah, they sent me another one, but still.

over the years, i've purchased 6 sets (bosch3's - 5 sets L98 and one set for an LTl) ) from the "preferred vendor" (assuming we're talking FIC). no issues and excellent customer service. the preferred vendor does provides matched sets - flow vs pressures, spray patterns, coil resistance, etc., and are plug and play due to the manifold to fuel rail distance. i'm guessing they've been around at least 20 years or so. the ebay set may have more unknowns. ask yourself - does the ebayer have the proper cleaning and testing equipment, or just some guy in his garage pumping carb cleaner while pulsing the coils? ebay MAY have the one year warranty but will they be around a year from now? guess it boils down to how lucky do you feel? the present set in my 85 was installed least 8 years ago - still runs great - no problems or issues. due to the labor involved swapping those things out, it's not one place i'd try to save a buck. just my 2-cent opinion.
I was asking from more of a logic perspective.
Supposedly all 8 of mine were changed a couple of owners prior to me buying the car. I don't know when they were done exactly, though.
But they don't match. Some of em are silver and some of em are black.
Anyway. Ity's just not running exactly right. Feels like the timing is off, but I was thinking maybe injectors because it feels like it could be fuel related. No codes or anything. And they all ohmd out at 17 with the engine off. Doiesnt mean they aren't all plugged up, though, even with using the Berryman's a few times.
So I was looking around at injectors and really the only doffernce I saw in them were cost. Thus the question.
You know how whe nyou;re driving a four door car and open a couple ofthe back windows and you get that kind of wind tunnel feel/sound?
Well that's kinfd of like the feel I get when I drive the car. It's weird.

Saving a few bucks isn't really why I asked the question. I invoked the cost difference because that's really the only difference I'm aware of.

The Bosch III have a better spray pattern. I have a set of newer factory injectors i pulled from my 89 last year when i put in a set of Bosch III. If you want to use any of them to pinpoint your problem let me know. Nothing wrong with them.

But I do appreciate the offer.
I took it out today and ran it up Rt 71 and then down 896 to the Home Depot there in Glasgow. I dunno if it's just me or what. Seems to drive fine. But there's still something that bugs me about the way it feels. I'm just going by pure feel, though. I just can't put my finger on it. I heard some dust shaking around in the mufflers when I replaced the cat the other day, too. But they were crimped to the crossover pipe too tight so didn't remove them and shake them out. I know the EGR is probably shot. I keep getting a code 32 and SES light when I'm cruising. That could have something to do with it. But if I'm gonna swap that out I may as well do the injectors at the same time anyway.
As an aside, I think that may have been only the second time I've driven it in rainy conditions. It was kind of fun, actually. I didn't even turn my radio on. Underbody got a good ''hosing'' so to speak.

I've been reading around the board about injectors. So learning a bit more about the differences in spray patterns and whatnot, with regard to what Joe was saying previously.

Well. I'f I'm gonna go to all of the trouble of uninstalling/reinstalling them, I may as well just buy a set of new ones and be done with it.

No problem. You change your mind let me know. I bought a set of the Bosch III from Southbay Fuel Injectors. Worked perfect. I also soaked my EGR in parts cleaner while I had the upper intake off. Wasn’t giving me any issues but I figured what the hell. It was absolutely filthy.

The installation is different. Make sure you follow his directions. He suggested dish soap for installation lol. It worked fine for me. I also disassembled the fuel rails and put in new o rings while I had everything apart. Before reinstalling the upper plenum and runners I charged up the injectors to make sure nothing leaked.

Thanks for the dish soap idea and of course the new O-rings are a must, well unless you are a sucker for pain, and thanks to all who recommend the South Bay site. Cheers.

By different, are you talking about just the dish soap rather than trans fluid or something like that?
I don't want to get something that is structurally different. Though I did see that they've installed extentions/adapters on the ones I was looking at.

I meant the way they install due to having the adapter. You put them in the intake first, then put the rails down afterwards. I had zero issues both times I did it this way.

I had actually bought a set from Ebay when I first got my 88 running. I figured since the car had been sitting with lots of water in the tank it would be a good idea to replace the entire fuel system.
Once I got them installed the car ran super rich. I ended up spending a bunch on tuning components (USB-OBD, chip burner, etc.). Spent weeks driving around, making changes, driving some more, rinse and repeat.
I picked up a parts car that ran and had the Bosch injectors. For grins I decided to swap injectors between the two. With all the fuel changes I had made trying to get the Ebay ones to work the car would barely run. Started with a fresh $6E tune and immediately the difference between the two was night and day.
All told, I had spent several hundred dollars and about 25 hours driving & tuning and it still wasn't right.
Lesson learned, sometime the cheap way isn't worth the hassle. I ended up spending much more than if I had just gotten the correct injectors the first time.

I always struggle with the one inner bolt that goes through the inside of the intake into the runner closest to the firewall on the driver's side. Make life easier on yourself and hit up Home Depot for a replacement bolt that accepts a socket head. It would be a snap to do at that point with an open end wrench.

Btw. Now that you've replaced your fuel tank and likely already filled it, the next time you fill up, can you make mental note to see how long and strong of a woosh sound you get when you take the fuel cap off to refuel again?
Ever since I replaced my tank, that thing wooshes pretty strong for a good five seconds. Maybe even a couple of seconds longer. I've read around the board but opinions seems to vary on it. I think it should be that way. It is a closed system, after all.

I was watching a video on Youtube where a guy was replacing his injectors. He had the same problem with the same bolt. Probably is a good idea if you're gonna be in there again. Which is probable at some point..
Btw. Now that you've replaced your fuel tank and likely already filled it, the next time you fill up, can you make mental note to see how long and strong of a woosh sound you get when you take the fuel cap off to refuel again?
